Same place as always - June 9th (tommorrow) at ASAP in Hayward. Just read the meeting notice. No you can renew your membership when you want, but if we do members only stuff, you can't participate.
It actually is not that bad. Most people joint BAR right before their first swap meeting (I did ). Since every year the swap happens more or less at the same time, the renewal has to happen in very timely way. I actually use swap meeting as a reminder for me to renew my membership .
